The two vectors $$\vec{a}$$ and $$\vec{b}$$ in the figure have equal magnitudes of $$14.8\mathrm{m}$$ and the angles are $${?}_1=26^{?}$$ and $${?}_2=101^{?}$$. Find (a) the $$x$$ component and (b) the y component of their vector sum $$\vec{r}$$, (c) the magnitude of $$\vec{r}$$, and (d) the angle $$\vec{r}$$ makes with the positive direction of the $$x$$ axis. (a) Number (b) Number
